Updating CronJob API version for Cloud Platform - deprecated Kubernetes v1.21
The batch/v1beta1
API version of CronJob is deprecated as of Kubernetes release v1.21, and will no longer be served as of v1.25.
Cloud Platform users are encouraged to ensure any CronJob manifests are migrated to use the batch/v1
API version, which is supported on our current cluster version (v1.24 as of writing).
Further details can be found within the Kubernetes deprecation guide
